the make and insmod refer to the instructions in the 'Install Drivers' section of Martin Smith's guide, where he describes how to get the latest version of 'dvb-kernel' from cvs and build it, then use insmod to install the modules you've built. I'm very new to linux, and while I've been really impressed with apt-get and yum, I'm fairly nervous about building anything and installing it for fear of screwing the whole system up. Hence my enthusiasm when I saw you had got things working, apparently without any building of code. > > Would you mind explaining how you knew which apt-get packages you > > needed, and how I would go about figuring out which I need for my Nebula > > card?

So it seems to me that the operating system regognises the card, but I thought that I then need another layer of drivers on top (the DVB stuff) to actually get the tv tuner to work - it that not correct? Martin Smith's guide talks about building/installing the DVB modules so that the output of 'dmesg' shows something like (his example): DVB: registering new adapter (TT-Budget/WinTV-NOVA-T PCI). tda1004x: Detected Philips TDA10045H. tda1004x: Detected Philips TDM1316L tuner. DVB: registering frontend 0:0 (Philips TDA10045H)... Now try as I might, I cannot get any 'DVB' messages to appear in that output, and when I try the next step (running dvbscan from the dvb-apps module on linuxtv.org) I get a message like this: [EMAIL PROTECTED] scan]# ./dvbscan dvb-t/uk-CrystalPalace > channels.conf scanning dvb-t/uk-CrystalPalace using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' main:1958: FATAL: failed to open '/dev/dvb/adapter0/frontend0': 6 No such device or address so it seems to me that my problem is installing this 'front-end' DVB driver which sits on top of the actual device's driver. > > Basically I checked what kernel modules were in the ATrpms repo:- > % yum list '*2.6.11-1.14_FC3-kmdl*' > > recognised cx88 as one that was relevant (you can use yum info if you > don't know what a package is addressing). > > Installing cx88 pulled in several of the other packages as dependencies, > unfortunately it missed saa7134 which is required, but is not detected, > so the first boot after did not load the drivers (errors show up > somewhere related to symbols with names like saa*).

This is a good point, might be worth forking out for another more widely-used card rather than trying forever with this one. I know there are people out there that have got this working though, which is the infuriating thing... see http://www.dtvforum.info/lofiversion/index.php/t14427.html I notice in here he mentions 'did modprobe nxt600 && dvb-bt8xx to load these modules'. Not sure what that means yet, but I'm going to read up and try to get this to work, will post back results here when I make any progress. thanks for your help, Matt _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
